The present invention discloses a random controlled fuel cell power module. The random controlled fuel cell power module includes a power module system, a current detection unit, and a random control unit. The power module system is composed of at least two parallel-connected DC/DC converters, for providing the power for a load. The current detection unit detects a load current value of the load. The random control unit reads the load current value and randomly assigns a control mode to activate the DC/DC converters according to the load current value, so that the DC/DC converters can be equally used. Therefore, the failure rate of the DC/DC converters is reduced, the life of the power module system is relatively prolonged, and the stability of the power module system is simultaneously increased.

The present invention discloses an image calibration device integrated with an optical locater. The image calibration device includes an image calibrator and the optical locater. The image calibrator can be arranged on an image capturing device to act as a reference to calibrate the image taken by the image capturing device. The optical locater has at least one pointing light source, which is located on a surface of the image calibrator, so that the pointing light source is used to assist in marking the location aimed by the image calibrator, thereby realizing the area captured by the image capturing device.

A method of forming a ring-type capacitor is provided. The method includes providing a substrate; forming a patterned mask layer on the substrate, the patterned mask layer defining a ring pattern; removing the substrate by using the patterned mask layer as a mask to form a ring-type trench in the substrate; the ring-type trench including an inner wall and an outer wall; and forming a capacitor structure on the inner wall and the outer wall of the ring-type trench.

There is provided a lateral flow diagnostic device that employs a phosphorescent particle. The particle includes, for example, an organic phosphorescent material encapsulated in a cross-linked halogen-containing polymeric matrix. The cross-linked halogen-containing polymeric matrix has at least one percent by mass weight of halogen atoms, and the cross-linked halogen-containing polymeric matrix shields the encapsulated phosphorescent material from phosphorescence quenchers.

A surgical guide instrument capable of omni-directional positioning and an omni-directional positioning unit thereof are provided. The surgical guide instrument includes the omni-directional positioning unit, which is coupled with the surgical instrument. The omni-directional positioning unit is configured as a pyramid, and a plurality of reflectors is deposited on vertices of the pyramid, respectively. As the reflectors of the omni-directional positioning unit are arranged as a three-dimensional pyramid, the omni-directional positioning unit can be connected in any position to the surgical instrument and be detected correctly by a surgical guide system, thereby reducing surgical complexity.

A spine fixation device is provided. The spine fixation device includes a bone screw, a fixation carrier, and a first locking member. The fixation carrier is rotatably coupled to a fixation unit of the bone screw. The first locking member conjugates the fixation carrier and the bone screw together. A screw unit of the bone screw is implanted into a vertebra. As the fixation carrier is rotatably coupled to the bone screw, the bone screw remains fastened to the vertebra while the fixation carrier is rotated. Through rotational adjustment of the fixation carrier, U-shaped openings of the fixation carrier are adjustable in direction. Thus, the disposition angle of a rod disposed in the U-shaped openings is easily adjustable by rotating the fixation carrier. As a result, the rod can fit an angle of the spine while surgical complexity is reduced.

A fuel cell stack with transparent flow pathways and bipolar plates thereof are provided. The fuel cell stack includes at least one membrane electrode assembly (MEA) and at least one pair of bipolar plates. Each bipolar plate includes a transparent flowing path plate and a current collector. Each MEA is interposed between two corresponding bipolar plates so that power generated by each MEA is transmitted through the current collectors disposed respectively on margins of adjacent ones of the transparent flowing path plates. The transparent flowing path plates allow the production of liquid water in the fuel cell stack to be monitored in real time from outside the fuel cell stack, so as to prevent flow pathways of the transparent flowing path plates from being blocked and thereby maintain the efficiency of power generation of the fuel cell stack.
摘要:
An embodiment of error concealment method for a bitstream is provided. The method first detects an error in a current frame of the bitstream, and when the error is detected, an error concealment procedure is performed on the current frame, starting from a first macroblock thereof preceding a second macroblock associated with the detected error.
摘要:
A method for reducing odor is provided. The method comprises forming a coordination complex between a transition metal and a polydentate compound, and contacting the coordinated complex with an odorous compound. The transition metal provides one or more active sites for capturing the odorous compound. In some embodiments, the polydentate compound may be a polyalkylimine, such as polyethyleneimine, polypropyleneimine, or a dendrimer thereof.
摘要:
An electrical adapter assembly for connecting a first hard disk drive and a second hard disk drive is provided. The electrical adapter assembly includes a connector capable of electrically inserting into the first hard disk drive, a printed circuit board (PCB) module electrically connecting the connector, and a loading member for loading the first hard disk drive. The PCB module includes a chip for controlling data transfer between the first hard disk drive and the second hard disk drive. The loading member includes a base and at least two guiding portions pivotally attached on the base to allow the first hard disk drive to be able to slide between the at least two guiding portions.
